[Phillip Powell]

Your code implementations work!  In Mozilla only.. :(  Fails in IE, 
Opera and Konqueror.. :(

Apparently IE, Opera and Konqueror look for a form element name to be 
alphanumeric construct only (e.g. "move", "move0", "move_move", 
"move-move"), but not "move[]", whereas Mozilla (and I believe Netscape 
but can't test that to know) are more forgiving of "move[]"..

I've tried numerous script examples and they all work in Mozilla and 
fail in IE the moment I use "move[]" instead of "move".

<script>
<!--
  function selectAll(formElementName) {
   if (document.imageForm.select_all.checked) {
    for (i = 0; i < document.imageForm.length; i++) {
     if (document.imageForm.elements[i].type == 'checkbox' && document.imageForm.elements[i].name == formElementName) {
      document.imageForm.elements[i].checked = true;
     }
    }
    document.imageForm.deselect_all.checked = false;
  }
 }

 function deSelectAll(formElementName) {
  if (!document.imageForm.select_all.checked || document.imageForm.deselect_all.checked) {
   for (i = 0; i < document.imageForm.length; i++) {
    if (document.imageForm.elements[i].type == 'checkbox' && document.imageForm.elements[i].name == formElementName) {
     document.imageForm.elements[i].checked = false;
    }
   }
   document.imageForm.select_all.checked = false;
  }
 }
